Final answer:
The statement about roots at the base of aerial stems developed from adventitious buds being true reflects the ability of plants to grow adventitious roots for additional support and in response to environmental conditions.
Step-by-step explanation:
The statement 'These roots are found at the base of aerial stems that developed from adventitious buds' is true.
Adventitious roots are roots that grow from parts of the plant other than the traditional root system, such as from stem tissues.
In many plants, adventitious roots can arise from the base of aerial stems, especially after the activation of adventitious buds.
These roots help support the plant and can be an essential adaptation for plants that grow in challenging environments or that have a climbing or sprawling growth habit.
Such roots offer additional support and can also aid in nutrient and water absorption depending on the environment.
This is different from apical meristems that are located at the tips of roots and stems, responsible for primary growth and elongation.
Adventitious roots contribute to secondary growth and can also arise in response to damage or environmental stresses, demonstrating the remarkable plasticity of plant growth.
